Road Asphalt Crack Sealant
Product Introduction
Road asphalt joint sealant is a core functional material specially used for sealing repairing cracks and joints in the field of road maintenance. It is mainly based on petroleum asphalt, and its performance is optimized by adding modifiers such as SBS, waste rubber powder, and polyurethane It is a key material for delaying the development of pavement diseases and extending the service of roads.
Product types
Classified into 5 categories by industry standards, namely high-temperature type general type, low-temperature type, cold type and severe cold type, which are adapted to different regions with minimum temperatures not lower than 0℃, -10℃ -20℃, -30℃ and -40℃.

Performance Features
Strong Adhesion: Closely adheres to seam walls of asphalt and concrete pavement, and will not debond or delaminate as the cracks deform. 2. High Elong and Toughness: After solidification, it can reach a maximum elongation of 8 times and deform synchronously with the temperature fluctuation of, greatly reducing the probability of secondary cracking. 3. Weather and Aging Resistance: Possesses excellent UV resistance, water damage resistance and resistance. Under normal working conditions, its service life can reach 3-5 years, and some special antifreeze can work stably for a long time in extremely cold environments at -40. 4. Sealing and Waterproofing: With strong fluidity, it can penetrate the bottom of cracks, completely block the channels for water to invade the road base and avoid secondary diseases such as subsidence and potholes on the pavement.
Construction Process
1. Pre-treatment: Thoroughly remove loose soil and inside cracks/joints using a high-pressure air blower, ensuring no standing water or debris remains in the.
2. Material Preparation: For hot-melt products, put them into a dedicated joint furnace and heat uniformly until completely melted. For cold-pour products, fully stir evenly after unsealing.
3. Grouting: Grout uniformly along crack from bottom to top. The colloid should fully fill the space without gaps, with its surface slightly higher than reserved settlement space of the road surface. For wide cracks exceeding 15mm in width, add an appropriate amount of aggregate and gr in a mixed state.
4. Traffic Opening: Hot-melt products can be opened to traffic after cooling for 2-3. For cold-pour products, spread fine sand on the surface after pouring; they can be quickly opened to traffic after surface drying for30 minutes.
